The rotor of a hysteresis motor is made of ceramic permanent magnet material, which causes:
Right Answer is:
No eddy current losses
SOLUTION
The rotor of the hysteresis motor is made up of ceramic permanent magnetic material, therefore, it is difficult to set up an eddy current in such a rotor due to the high resistivity of magnetic materials like ceramic. Hence there is no eddy current loss but only hysteresis loss.
